A novel MIMO antenna design using Characteristic Modes

A novel design of Multi-Input Multi-Output (MIMO) antenna is presented. Pattern and polarization diversity is created using Characteristic Modes (CM) theorem and reduces the envelope correlation and isolation between the ports. So a printed structure consists of two circular patches is proposed for MIMO application. This structure is fed by two slotted coupled feeds configuration. The proposed antenna has been simulated in Ansoft HFSS software and simulation results are presented.
